This makes it easier for us to add resolver scenarios by 1. Rewriting the scenario package generation in Rust 2. Serving scenario packages from memory in a wiremock index 3. Rewriting the scenario test case generation in Rust 4. Dropping all dependencies on packse / the packse index --------- Co-authored-by: Codex <noreply@openai.com>

description = """There are two packages, `a` and `b`. We select `a` with `a==2.0.0` first, and then `b`, but `a==2.0.0` conflicts with all new versions of `b`, so we backtrack through versions of `b`.
|
|
|
|
We need to detect this conflict and prioritize `b` over `a` instead of backtracking down to the too old version of `b==1.0.0` that doesn't depend on `a` anymore."""
